Cranleigh, Methodist Church. Map evidence implies the church was built after 1871. By 1896, a small Mission Hall stood on the site, and by 1915 it had been replaced by a "Meth. Church (Wes.)". This article, from 2004, mentions the churches recent centenary, so it must have been built in 1904. Another view. TQ 055 392.© Martin Richter (2012). Link.

Sunbury-on-Thames, St. Ignatius of Loyola (R.C., 1869) on Green Street. TQ 1005 6970. Link. Open Door Church Centre, on Rooksmead Road is part of the Commission family of churches. The church also holds services at Sunbury Manor School, on Nursery Road. This was originally a Congregational Church (1904). It may have been built as a replacement for an Independent Chapel of 1792 which stood at TQ 1119 6878, and which (from map evidence) was demolished in the final years of the 19th century. TQ 1020 6915. Link. Both © Martin Richter (2018).
Sunningdale, St. Alban. Another postcard from Judy Flynn's collection, previously in the Unknown section. It was thought that it might possibly be the demolished one mentioned here (just beneath the church photo). The postcard was posted in 1905. Howard Richter advised that the footprint of the church in the postcard is not contradicted by map evidence, and the grid reference would have been SU 943 660. It appears to have been built between 1900 (not on a map of that year), and before 1915. Another old postcard shown here (scroll down) is again entirely consistent with this being the Sunningdale St. Alban's. It also says that it was a daughter church to Windlesham (St. John the Baptist).
Sutton, St. Nicholas (1862-4). Labelled only as Sutton Parish Church, I (wrongly) thought this postcard (from Reg Dosell's Collection) would be fairly easy to identify. Initially "solved" as Boldmere Church (which admittedly looks very similar), thanks are due to Pete Knight for finally unravelling this mystery. Built on the site of an older church, or churches, one is shown here in an old engraving from Cracklow's "Churches and Chapels in Surrey", published in 1827. © Colin Waters Collection. Link.

Thorpe, St. Mary, on Church Approach. TQ 0239 6865. An old postcard from Reg Dosell's Collection, previously in the "Unknown" section, and identified by Greg Mishevski. Another unknown also proved to be of this church - Avril Hodgkins has an old family photo which she was trying to identify. Her family has connections with the Wolverhampton area, and with Somerset, but it proved to be in neither. It was also identified by Greg Mishevski. Avril has since visited the church and taken these photos - 1, 2, © Avril Hodgkins (2020). Another view, © Karel Kuča (2011). Link. Grade II* listed.

Walton-on-the-Hill, St. Peter, as seen by Streetview in 2018. The church website has a number of rotating photos, here. The mid-C12 lead font is a rarity. Its subject matter is variously described as the apostles, or (in the appended listing), virtues and vices. Detail. Piscina and sedilia. All © Christopher Skottowe (1963). TQ 2237 5509. Grade II* listed. Old O.S. maps indicate Chapel (Remains of) a short distance west of the church, at TQ 2217 5514. It's site isn't visible on Streetview, and I haven't been able to discover anything about on-line. Christchurch (U.R.C.) stands on Walton Street, at TQ 2254 5520. It pre-dates a map of 1956, and was seen by Streetview in 2021. Link.
